In the tenth century, the Viking king Harald Blåtand (Harald Bluetooth in English) united large swathes of modern-day Norway and Denmark under his rule. Fast-forward to 1994, when Ericsson’s R&D teams started investigating ways to connect computers and the “smartphones” of the day without cables. In 1997, Jim Kardach proposed the name “Bluetooth” for the new technology that would unify communications protocols like King Harald had united Scandinavia.
A Bluetooth profile is a set of pre-determined capabilities and a customized stack, determined by the type of operation intended. Profiles make it much easier to design for, implement and manage the very wide variety of Bluetooth operations needed for an application.
